3D printing and traditional combination of research and development of oil and water separation skimmer
On May 24, the reporter learned from the Lanzhou Institute of Chemical Physics of the Chinese Academy of Sciences that the material surface interface group of the institute combined 3D printing manufacturing technology with traditional surface engineering methods to develop an oil-water separation oil skimmer, thus realizing the surface oil slick. Efficient separation and collection. Related results have been published in the "Advanced Materials Interface" magazine.
In recent years, inspired by the super-hydrophobic surfaces of nature such as lotus leaves, water-legged legs, flaps, etc., bionic (super) hydrophobic-lipophilic porous materials have attracted widespread attention and have shown great application prospects. However, porous materials achieve oil-water separation primarily by storing oil in their micro-nanometer pores. This results in limited oil storage capacity, low absorption capacity, and subsequent processes such as extrusion, which are difficult to clean and have poor reusability.
With the advantages of 3D printing technology in computer-aided design, free manufacturing processing and device molding, the Lanzhou Institute of Materials Surface Interface Group developed a platform for oil and water separation components based on 3D printing technology, and manufactured by oil and water. An oil skimmer consisting of a mesh cap and a bottom container. The 3D printing mesh cap with excellent hydrophobicity and lipophilicity can realize the rapid separation of the oil floating oil by using the filtering effect, and store it in the bottom container, thereby realizing the high-efficiency synchronous separation of various oils such as gasoline, edible oil and mineral oil. collect.
It is understood that 3D printing manufacturing technology can design and manufacture oil/water separation components with different pore sizes, sizes and capacities according to actual needs. The oil and water separation component manufacturing platform based on this technology is expected to be directly mounted on the ship to carry out rapid, efficient and low-cost marine cleaning work at the oil spill site.
